Less air leakage.
More comfort & savings.

Typical residential homes have air leakage paths commonly found around windows, doors, foundation, under the eves, and around the chimney. Air Leakage is measured by Air Changes per Hour (ACH). The amount of air leakage can make a significant difference in the comfort of your home and the heating and cooling energy use year after year.

The lower the air changes per hour, the tighter the housing unit—meaning less air leakage, more comfort and more savings. Our housing units are built to reduce heating and cooling energy by up to 50%* as compared to Standard Code Built Homes.
